To reset all settings in File Explorer in Windows 11, you can restore the default settings for both Folder Options and the File Explorer layout/view settings. Here's how:

---

🔧 Method 1: Reset via Folder Options

1. Open File Explorer.

2. Click the three-dot menu (...) on the top toolbar, then select Options.

3. In the Folder Options window:

   • Under the General tab, click Restore Defaults.

   • Switch to the View tab and click Restore Defaults.

4. Click Apply, then OK.

🔄 Method 2: Reset All Folder View Customizations (Registry Reset)

This will reset all folder views back to their defaults.

⚠️ Caution: This involves editing the Windows Registry. Be careful, or back up your registry first.

1. Press Win + R, type regedit, and hit Enter.

2. Navigate to:

   HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Bags
   

3. Right-click the Bags key and choose Delete.

4. Then delete the BagMRU key in:

   HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\BagMRU
   

5. Restart your PC or log out and back in.

This will reset folder view settings (e.g. details, large icons, grouping) across File Explorer.
